Punched sheet
Sheets punched to a defined hole pattern, pitch and open area. Because the pattern is set at the design stage, the sheet can be tuned for airflow, acoustic performance or visual screening.
Also known as: Perforated plate · Punched metal sheet · Perforated screen · Hole punched sheet

Typical configuration
Open area 40%–70%
High open area keeps the pressure drop low.
Typical configuration
Round holes, staggered pattern
Open area is set by the acoustic design.
Typical configuration
Small holes with a protective margin
Visibility with a physical barrier.
Typical configuration
Powder coated or anodized, custom pattern
Visual screening and light control.
Open area is the proportion of the sheet that is hole, expressed as a percentage. For a staggered round-hole pattern it depends on the hole diameter and the pitch between holes. Raising the open area increases airflow but reduces sheet strength.
A hole smaller than roughly the sheet thickness is difficult to punch cleanly, and a hole far larger than the thickness can distort the sheet. The practical ratio between hole size and thickness has to be kept within workable limits.
Staggered patterns give a higher open area for the same hole pitch and a more even appearance. Straight rows are used where the holes must line up with a fixing grid or where a specific visual effect is wanted.
